Freewheel - Spacer for 1-Speed

Description

Single Speed Freewheel Spacer

This is a thread-on spacer that positions a single speed freewheel for proper chain alignment.

Threaded for ISO-standard 1.375" x 24 TPI freewheels (34.92 x 1.058 mm) 24mm (15/16 inch) length overall, so it will increase your chainline by about 12mm (just under 1/2 inch).

These use a tight thread-fit to prevent loosening, we install them by carefully mounting the spacer in a bench vise (it has wrench flats), then screwing the wheel onto it (be careful of cross-threading), and then installing the freewheel on the outside last.
